No harm in not having coolant in there, it only goes to the throttle body.

I have only a few pictures of the last one I did.

Two ports.


I used Teflon tape, but it really didn't hold up. Red RTV worked. There'* not a lot of material to seal. So make the plugs flush, RTV over it, then use the nickel to seal the top.

Also can this be done if UIM is leaking around the egr pipe and still use the same UIM ??

Its not the gas mileage that gets to me. Its the fact that we may see 5 dollar a gallon gas. No matter how good your gas mileage is, its gonna cost more to drive somewhere.

/me ends dystopian rant.

Yes, this blocks any coolant from getting in to the UIM.

so there are just 2 coolant ports
, one on either side of the stove pipe ??
Use 1/4" pipe tap and brass plugs ??
then you said remove something from the UIM gasket ?? I dont get where the nickle comes into play ??

dont worry gas prices will come back down, as soon as people quit driving so much they will drop, this is a big game

On the UIM gasket there is a rubber O ring for the coolant passages. You remove those and put a nickel in it'* place with red RTV

Dan, your a man of few words,lol

Here are the things I would like you to answer

1) Are there ONLY 2 coolant ports ?

2) did you use a 1/4" NPT tap ?

3) Brass plugs ?

4) Can this be used on a leaky UIM ?

5) so I need to remove 2 orings on the UIM and repace with nickles, right ?

Thank you !

Yes, 2 ports.
Yes, 1/4" NPT tap, you will need to enlarge the hole a little.
Brass plugs are fine
Yes, this is used on a leaking UIM, this is the fix
Remove the O rings from the gasket, (coolant passages) a nickel fits perfectly. Seal it all up with red RTV

so even if the uim has a hole in it you can still use it with this repair ??

2) why did the factory have coolant going thru the UIM ?

3) so i need to drill the holes out a little BEFORE using the tap ??

4) will everything else seal up ok if I reuse the leaky UIM ??

Thx
